Hi Guys,
I have loaded thousands of plated 115 grain plated round nose Berry and Ranier for 9mm with .37 CC Lee autodisk that produces charges 4.0 to 4.4 grains of Tite Group and they all shot well from 3 different Kahrs, XD, Sig, Ruger, everything I own. My press is set up to seat the bullets at 1.144 COL.
My brother's Kahr CW9 is producing FTF with light, off center strikes with my reloads. Sent it to Kahr and it came back with same problem. It shoots factory Hornady Critical Defense (short ogive) perfectly. Fellow at the Kahr forum suggested seating bullets a bit deeper. How much deeper can I seat the 115 gn bullets safely? Ranier gave me 1.14 minimum COL for 9mm RN when I started loading, but Lee Book shows 1.125 for 115 Jacketed RN and 4.5 grains of Titegroup. Seems to me that 1.125 should be safe. Isn't a jacketed bullet going to have more friction resistance and hence higher pressure than a plated bullet? Second question is: can I run the 200 of these I just made w few weeks ago through just the bullet seater down to 1.125? Thanks in advance, shovel99
